* switch IPv6 advanced API from RFC2292 to RFC3542 (2292 is superseded by 3542).itojun2006-12-091-7/+6
| | | | | | | | | | the kernel still handles RFC2292 set/getsockopts, so that compiled binary has no trouble running. userland sees RFC3542 symbols only on header file so new code has to use RFC3542 API. bump libc shlib minor for function additions. tested on i386/amd64 by jmc, i386 by brad. checked by deraadt.
* The current implementation to handle control options is broken as soon asclaudio2006-11-271-21/+24
| | | | | | SO_REUSEADDR and multicast/broadcast comes into play. Model the ip_savecontrol handling after the rip_input version which works. Problem found by Simon Kelley. OK henning@ michele@
* Call ip_savecontrol() in the multicast codepath of udp_input() similar toclaudio2006-07-171-1/+7
| | | | | | the INET6 code. With this it is possible to use e.g. IP_RECVIF to get the incomming interface. SOCK_RAW is not affected by this. Problem found and fixed by Michele 'mydecay' Marchetto. OK markus@
* Make number of varargs passed to ip_output match reality.pascoe2006-06-151-2/+2
| | | | henning@ claudio@ ok
* Make savecontrol functions more generic and use them now for raw IP too.claudio2006-05-291-53/+4
| | | | | Additionally add the IP_RECVIF option which returns the interface a packet was received on. OK markus@ norby@

| | | | | | | | need to save/restore it. - inp->inp_laddr should be set _before_ calling pcb_disconnect(). otherwise pcb_disconnect() calls pcb_rehash() with the old laddr. [ currently this is not a problem since the hash ignores laddr ] tested by pedro

* make pf use one mbuf tag instead of 6 distinct ones. use a little structhenning2005-10-171-5/+11
| | | | | | | | | in the data part for the data from the previously distinct tags. look up the tag early and carry a pointer to it around. makes the code easier and saves some tag lookups and thus helps performance, as proven by tests run by Schberle Dniel <Schoeberle.Daniel@aamtech.hu> Initially hacked up somewhere over the atlantic ocean in an A330 early testing reyk and moritz, "put it in" theo
* Experimental support for opportunitic use of jumbograms where only some hostsmcbride2005-05-271-2/+3
| | | | | | | | | | | | | | on the local network support them. This adds a new socket option, SO_JUMBO, and a new route flag, RTF_JUMBO. If _both_ the socket option is set and the route for the host has RTF_JUMBO set, ip_output will fragment the packet to the largest possible size for the link, ignoring the card's MTU. The semantics of this feature will be evolving rapidly; talk to us if you intend to use it. ok deraadt@ marius@

* Mbuf tag tcp and udp packets which are translated to localhost, andmcbride2003-12-081-4/+6
| | | | | | | | | | | | | use the the presence of this tag to reverse the match order in in{6}_pcblookup_listen(). Some daemons (such as portmap) do a double bind, binding to both * and localhost in order to differentiate local from non-local connections, and potentially granting more privilege to local ones. This change ensures that redirected connections to localhost do not appear local to such a daemon. Bulk of changes from dhartmei@, some changes markus@ ok dhartmei@ deraadt@
